PRINTING DEVICE.

Patented May 14, 1912.

To all whom it may concern Be it known that I, JOSEPH S. DUNCAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful which the following. is a specification.

This invention relates to that class of printing devices lin which a rinting plate is carried by a frame and which is adapted to be stored in accordance with a card index system and run through an addressing or other printing machine foi'a taking an impression therefrom.

The devices are used principally for printing addresses and are generally employed by those who send out many bills regularly to the same customers, such as gas companies, electric light companies and telephone companies. The are also largely used by publishers and 0t er concerns that have large mailing lists.

When a change in address occurs itis necessary to prepare anew printing plate and it is desirable to reduce the cost of thus fmaintaining the lists up-to-date by avoiding the necessity of replacing the entire plate. In the case of a telephonecompany,

for example, it may be theta .telephone number will be permanently located at a certain address and thus if the subscriber old subscriber for that of a new subscriber without changing the remainder of the printing device. This may occur in many other uses of these'printing devices but the example above noted will be. sufiicient to indicate the purpose of my invention.

The object of my invention is to reduce the expense of maintaining a system of printing devices of this general character by providing for the renewal of so much only of the printing device as is necessary when changes occur. And a further object of the invention is to provide a sectional printing plate for a printing device of this charactenthe sections being readily insertible in and removable from the plate and .view on the line 3-3 of Fig. 1.

so as not to obstruct the face of the printing plate.

In the accompanyin drawings illustrating one embodiment 0 my invention Figure 1 is a front view of the invention. Fig. 2 is a bottom edge view. Fig. 3 is a sectional Figs. 4 and. 5 are detail views of the two sections of the printing plate.

The. frame 6 is provided at its ends with spacing flanges 7 and at its top and bottom with beads 8 and 9. A card 10 is remov- -ably held in place beneath the bead. 8 and the lips 11 bya stop 12.

The printing plate consists of two sections 13, 14, one arranged alongside of the other and located below the card. In the embodiment of the invention selected ror illustration the section 13 is both the main and the permanent section and the section 14 is arranged above the main section and is the renewable section. Obviously thesection 13 may be renewed while the section 14 remains permanent and the position of the two sections may. be reversed. It is also apparent that if a new section 14 is substituted for that section now in the frame the present section may be used in another frame. In other words, by exchangingsections from various frames it may be possible to maintain a system of address printing devices of this character with changes as they occur and without necessitating the production of any new sections whatever. Thus the expense of maintaining the syssimilarly reduced.

The section 13 is held in place on the frame beneath the bead 9 and the lip 15 by a spring catch 16, or other suitable means. The section 14 is held in place alongside the section 13 beneath the lips 15, 17 and 18 and is secured, against endwise movement by a projection 19 on the section 13 which enters anotch 20 in the section 14. In inserting the sections in the frame the section 14 will slid into place sidewise after which the section 13 is slid into place endwise.

It is desirable to have the section 14 of greater width than is absolutely necessary for the. line of type thereon so that the lips 17 may clear the inking device and other parts of the addressing machine. For this purpose the section 14 is 'provided with proj ections 21 arranged on its opposite edges in staggered relation to each other These projectionsincrease the maximum width of the "section 14; and they are arranged at one edge of the, projections, vare disposed a sufficient distance from the line of t pe to be clear of 7 the mechanism of the addressing machine. The sections 14 can. be stamped out ofa lliqsheet of metal without loss ofmetal for the projections on one side edge lieopp0s1te Y complementary recesses on the other-side ed e." yinvention is simple in character and yet it is particularly important for .users of printing devices of; this character incertain" .lines of business, particularly where numerouschanges in ad resses' are occurring from time to time} It will'be readily perceived that in a'case of a telephone company, where subscribers aremoving from place to place in the same territory, the necessity for mak- 7 ing newplates will be reduced to a minimum because the sections can be interchanged readilyzand easily to maintainthe system.
